BACKGROUND OF THE INVENTION

[0001] The present invention relates to a height adjustable flexible shoe and more particularly pertains to allowing a person to easily adjust a heel of a shoe to reach a proper height.

[0002] The use of footwear heel devices is known in the prior art. More specifically, footwear heel devices heretofore devised and utilized for adjusting heel sizes are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art that have been developed for the fulfillment of countless objectives and requirements.

[0003] By way of example, U.S. Pat. No. 6,021,586 to Bucalo discloses a shoe with an adjustable heel assembly for positioning at a number of heights. U.S. Pat. No. 2,707,341 to Romano discloses a shoe with convertible heels capable of extending or retracting and locking into position with a button assembly. U.S. Pat. No. 3,056,217 to Tholander discloses an attachable heel lift device comprised of a bore and dowel assembly.

[0004] While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a height adjustable flexible shoe for allowing a person to easily adjust a heel of a shoe to reach a proper height.

[0005] In this respect, the height adjustable flexible shoe according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of allowing a person to easily adjust a heel of a shoe to reach a proper height.

[0006] Therefore, it can be appreciated that there exists a continuing need for a new and improved height adjustable flexible shoe that can be used for allowing a person to easily adjust a heel of a shoe to reach a proper height. In this regard, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

[0007] In the view of the foregoing disadvantages inherent in the known types of footwear heel devices now present in the prior art, the present invention provides an improved height adjustable flexible shoe. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved height adjustable flexible shoe that has all the advantages of the prior art and none of the disadvantages.

[0008] To attain this, the present invention essentially comprises a shoe upper portion having an open upper end, a closed lower end, and a body portion therebetween. The open upper end is dimensioned for receiving a foot therein. The closed lower end has a toe portion and a back portion. The back portion has a first heel portion extending downwardly therefrom. The first heel portion has a lower end with an aperture formed therein. The body portion comprises an adjustable elastomeric material. A second heel portion is adapted for removably coupling with the first heel portion of the shoe upper portion. The second heel portion has a wide upper end and a narrow lower end. The wide upper end has a protrusion extending upwardly therefrom. The protrusion is dimensioned for snap engaging the aperture in the lower end of the first heel portion of the shoe upper portion. The narrow lower end has an aperture formed therein. A third heel portion is adapted for removably coupling with the second heel portion. The third heel portion has a wide upper end and a narrow lower end. The wide upper end has a protrusion extending outwardly thereof.

[0009] The protrusion is dimensioned for being selectively snap engaged with the aperture of the first heel portion and the second heel portion.

[0010] There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

[0024] With reference now to the drawings, and in particular, to figures one through two thereof, the preferred embodiment of the new and improved height adjustable flexible shoe embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.

[0025] Specifically, it will be noted in the various figures that the device relates to a height adjustable flexible shoe for allowing a person to easily adjust a heel of a shoe to reach a proper height. In its broadest context, the device consists of a shoe upper portion, a second heel portion, and a third heel portion. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

[0026] The shoe upper portion 12 has an open upper end 14, a closed lower end 16, and a body portion 18 therebetween. The open upper end 14 is dimensioned for receiving a foot therein. The closed lower end 16 has a toe portion 20 and a back portion 22. The back portion 22 has a first heel portion 24 extending downwardly therefrom. The first heel portion 24 has a lower end 26 with an aperture 28 formed therein. The body portion 18 comprises an adjustable elastomeric material. Note FIG. 2.

[0027] The second heel portion 30 is adapted for removably coupling with the first heel portion 24 of the shoe upper portion 12. The second heel portion 30 has a wide upper end 32 and a narrow lower end 34. The wide upper end 32 has a protrusion 36 extending upwardly therefrom. The protrusion 36 is dimensioned for snap engaging the aperture 28 in the lower end 26 of the first heel portion 24 of the shoe upper portion 12. The narrow lower end 34 has an aperture 38 formed therein.

[0028] The third heel portion 40 is adapted for removably coupling with the second heel portion 30. The third heel portion 40 has a wide upper end 42 and a narrow lower end 44. The wide upper end 42 has a protrusion 46 extending outwardly thereof. The protrusion 46 is dimensioned for being selectively snap engaged with the aperture 28,38 of the first heel portion 24 and the second heel portion 30.

[0029] In use, the person wearing the present invention can adjust the height of the device 10 by removing the second and third heel portions 30,40. When all three of the heel portions 24,30,40 are in place, the present invention resembles a high-heel shoe. Incremental removal of the third heel portion 40 and the second heel portion 30 will lower the height of the present invention.

[0030] As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0031] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0032] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
